faq:
  - q: "Which stablecoin is better for business payins, USDC or USDT?"
    a: "Neither wins everywhere. Pick by where your recipients are, which networks they use and which regulators you answer to. USDC is the usual choice for US and EU-facing flows. USDT is common where recipients already hold it, especially in some emerging markets. A payin API that supports both lets you decide per customer instead of company-wide."
  - q: "Do my customers need to hold USDC or USDT to pay me?"
    a: "No. In a payin, the payer sends fiat, such as an ACH, wire, Pix or SPEI transfer, and the provider converts it. Only the recipient wallet receives stablecoins. With BlindPay, the payer never touches a stablecoin, and the stablecoin choice is a field on the payin quote."
  - q: "Can I accept both USDC and USDT with BlindPay?"
    a: "Yes, where the network supports it. BlindPay payin delivery supports USDC and USDT on Ethereum, Polygon and Solana, and USDC only on Base, Arbitrum and Stellar. You set the token on each payin quote, so one integration can serve recipients who want different stablecoins on different networks."
  - q: "Does the GENIUS Act or MiCA change which stablecoin I can use?"
    a: "They can, through your providers more than through you. MiCA sets rules for stablecoins offered in the EU, and the GENIUS Act sets rules for payment stablecoins sold to US persons. Neither is a licence you apply for as a merchant. Ask your provider which tokens it supports in each region and review that list regularly."
  - q: "Is BlindPay a stablecoin issuer?"
    a: "No. BlindPay is payment infrastructure. It converts fiat deposits into stablecoins issued by others, such as USDC from Circle or USDT from Tether, and delivers them to a wallet. Because BlindPay is not an issuer, it works alongside issuers and does not compete with them on reserves or redemption."
  - q: "Where does the stablecoin in a BlindPay payin come from?"
    a: "BlindPay converts the fiat deposit and sends the stablecoins on-chain to the destination wallet you set on the payin quote. That wallet is either a customer-controlled blockchain wallet or an optional BlindPay-managed wallet (beta). On Stellar mainnet, deliveries come from a published BlindPay treasury address you can use to reconcile."

Choose the stablecoin for payins by where your recipients are, which networks they use and which regulators you answer to. Circle issues USDC, the common default for US and EU-facing flows. Tether issues USDT, which is widely held in some emerging markets. BlindPay delivers either one, so the choice can be per recipient.

In a payin, the payer sends fiat and never needs to hold either token. That changes the question from "what do my customers hold?" to "what should the recipient wallet receive?"

## Key takeaways

- A payin starts with fiat. The payer does not need USDC or USDT, only the wallet that receives the stablecoins does.
- USDC and USDT are issued by different companies under different rules. Regulation, reserves and network support differ.
- Network support is uneven. In BlindPay payin delivery, USDT is available on Ethereum, Polygon and Solana, while Base, Arbitrum and Stellar carry USDC.
- You do not have to bet on one token. A payin API with both lets you route by recipient, network or region.
- Laws such as MiCA and the GENIUS Act reach you mostly through your provider's token list.

For a broader comparison that includes card and payout use cases, see [USDC vs USDT for payments](/resources/more/usdc-vs-usdt-for-payments). This page covers only the payin side. For the full flow, start with [what a stablecoin payin API is](/resources/more/what-is-a-stablecoin-payin-api).

## What are USDC and USDT?

USDC and USDT are stablecoins: digital tokens on a blockchain designed to track one US dollar. A blockchain wallet is the address that holds them. Circle issues USDC, and Tether issues USDT. Each issuer publishes information about its reserves and redemption terms on its own site.

Both tokens exist on several networks (a network, or chain, is the blockchain a token moves on). BlindPay is a payment infrastructure provider, not an issuer, so it complements issuers such as Circle rather than replacing them.

## Which is better for payins?

For payins, the better token is the one your recipient wallet can use on the network you deliver to. Fiat arrives, the provider converts it, and the stablecoin lands in the recipient's wallet. The payer's preference does not matter.

Use this decision table as a starting point. It reflects facts you can verify, with sources listed below.

| Question | USDC | USDT |
| --- | --- | --- |
| Issuer | Circle ([circle.com/usdc](https://www.circle.com/usdc)) | Tether ([tether.to](https://tether.to/en/)) |
| Reserve reporting | Circle publishes reserve reports at [circle.com/transparency](https://www.circle.com/transparency) | Tether publishes attestations at [tether.to/en/transparency](https://tether.to/en/transparency/) |
| EU position under MiCA | Offered by EU-regulated venues as an e-money token (see the [MiCA register at ESMA](https://www.esma.europa.eu/esmas-activities/digital-finance-and-innovation/markets-crypto-assets-regulation-mica)) | Check each EU venue and provider: availability for EEA users varies, and you should confirm it directly |
| US position | Subject to the GENIUS Act's issuer and distribution rules once they apply | Subject to the same Act, with a separate path for foreign issuers (see [the GENIUS Act and USDT](/resources/more/genius-act-usdt-foreign-stablecoin-issuers)) |
| Payin delivery in BlindPay | Ethereum, Polygon, Base, Arbitrum, Stellar, Solana | Ethereum, Polygon, Solana |
| Typical use | Businesses with US and EU counterparties | Recipients who already hold USDT, common in some emerging markets |

## How do regulations affect the choice (GENIUS Act, MiCA)?

Both laws regulate stablecoin issuers and service providers more than the businesses that accept payments. They still shape your choice because they decide which tokens your providers may offer in each region.

The GENIUS Act was signed on July 18, 2025. Its effective date is the earlier of 18 months after enactment or 120 days after final implementing regulations, according to the [enrolled text on Congress.gov](https://www.congress.gov/119/bills/s1582/BILLS-119s1582enr.htm). MiCA, Regulation (EU) 2023/1114 on [EUR-Lex](https://eur-lex.europa.eu/eli/reg/2023/1114/oj), applied its stablecoin titles from June 30, 2024 and the rest of the regulation from December 30, 2024. The transitional period for crypto-asset service providers ends no later than July 1, 2026.

For the dates in detail, see [the GENIUS Act and MiCA timeline](/resources/more/genius-act-timeline-key-dates) and [the MiCA explainer](/resources/more/mica-stablecoin-rules-explained). Ask your provider which tokens it offers in the EU and the US, and how it will handle changes.

## Which networks support each?

Network support depends on where each issuer has deployed its token, and on what your provider supports for payin delivery. In BlindPay payin delivery, the supported combinations are:

| Network | USDC | USDT |
| --- | --- | --- |
| Ethereum | Yes | Yes |
| Polygon | Yes | Yes |
| Base | Yes | No |
| Arbitrum | Yes | No |
| Stellar | Yes | No |
| Solana | Yes | Yes |

Source: the Stablecoin delivery table in the [BlindPay payins docs](/docs/payins). The [supported chains reference](/docs/kb/supported-chains) lists additional networks, so check it for the current set. Issuer deployments are listed at [Circle's developer docs](https://developers.circle.com/) and on [Tether's supported protocols page](https://tether.to/en/supported-protocols/).

If the recipient is on Base, Arbitrum or Stellar, the answer is USDC, because USDT is not delivered there. For network trade-offs beyond token support, see [the best network to off-ramp stablecoins](/resources/more/best-network-to-off-ramp-stablecoins).

## Do my customers need to hold either one?

No. The payer in a payin sends a bank transfer, a Pix code, a SPEI transfer or a card payment. They never touch USDC or USDT. The provider converts the fiat and delivers stablecoins to the recipient wallet.

That is the main difference from a crypto-native checkout, where the payer must already hold a stablecoin and the right network. If your payers are ordinary bank customers, the token choice is invisible to them. If your recipients are the ones who care, the choice sits on the receiving side only.

## Can I accept both?

Yes, as long as your provider supports both on the networks you use. With BlindPay, you set the `token` on each payin quote, and BlindPay detects the destination network from the wallet record. One integration can deliver USDC to one customer and USDT to another.

Here is an illustrative way to decide per recipient:

1. List the networks your recipient wallets use.
2. Check which tokens each network carries for payins (table above).
3. Ask each recipient, or your treasury team, which token they prefer on that network.
4. Set the `token` on the payin quote accordingly.
5. Review the choice when your compliance team updates its list of approved tokens.

## Choose USDC if, choose USDT if

Choose USDC if your recipients are US or EU businesses, if you deliver on Base, Arbitrum or Stellar, or if your compliance team wants issuer disclosures aligned with Western regulators. Choose USDT if your recipients already hold it, if they operate on Solana, Polygon or Ethereum and prefer it, or if local liquidity favors it. Choose both when your recipient base is mixed.

## Where does BlindPay fit?

BlindPay is a payment infrastructure provider. It does not issue stablecoins. A payin starts with a payin quote, which locks the payment method, amount, fee split and destination for 5 minutes. After the fiat deposit clears, BlindPay converts it and sends stablecoins to the destination you set on the quote.

- **Tokens and networks:** USDC and USDT on Ethereum, Polygon and Solana, and USDC on Base, Arbitrum and Stellar, per the [payins docs](/docs/payins).
- **Destination:** a customer-controlled blockchain wallet (`blockchain_wallet_id`) or an optional BlindPay-managed wallet (`wallet_id`, beta).
- **Fees:** per-transaction fees vary by rail and network and appear in the live quote before you create the payin. See [pricing](/pricing).
- **Virtual accounts:** for recurring bank deposits, see [virtual accounts for stablecoin payins](/resources/more/virtual-accounts-for-stablecoin-payins).
